Imogen seized the crown from the Hunger Games-inspired Katniss as the Number One girls’ name on Nameberry for 2013.

Charlotte, which had been the most popular girls’ name in previous years, now stands at Number Two, while Harper, now officially classified as a girls’ name with over 90 percent of the baby Harpers female, is a new entrant to the list at Number Three.

Our popularity lists are tabulated by ranking the unique page views each name attracts out of the over 20 million total views of our baby name pages in 2013.

Major trends in girls’ names we see based on our 2013 Popularity List:

It’s a common baby name dilemma: You love a name like Cora or Lila forever, holding it close as your own special secret choice, and then bang! Right when you’re finally in a position to use it, you discover it’s become a trendy new favorite, vaulting up the charts.

What are more unusual baby names that may relate to trendier names but are more distinctive?

Avalon – If you like Ava and Adeline, but want a name that’s more unusual, you might love Avalon. Avalon is the name of a mythical island paradise – literally, “island of apples” — that offers a fresh take on several trendier girls’ names. And okay, so it’s also a car name, but so are Mercedes and Portia.

There’s a new girl in town, and her name is Imogen — the breakout Number 1 among girl names on Nameberry for the first half of 2013.

Imogen unseated longtime favorite Charlotte as our most-viewed girl name so far this year. In third place we have another new entrant to the girl names list, Harper, which we’ve moved over from unisex given that over 90 percent of the babies named Harper are now female.

This list of Nameberry’s Top 100 girl names is based on over 8 million views of our name pages for the first half of 2013.

This list shows the influence of popular culture, news events, and celebrity on interest in names. Merida was an animated film heroine, while Clementine and Everly were girl names chosen by celebrities and Francine and Frances may be inspired by the new Pope.

And we see names in the lower half of the list moving up on the coattails of their more popular sisters: Elodie and Eloise are rising behind Eleanor, for instance, while Mae and Maisie follow Maeve. Ada is a new entrant at Number 92, and we predict will move up on the strength of the popular Ava, still strong at Number 12.

While many of the girl names popular with Nameberry visitors also rank high on the U.S. baby names popularity list, others are outliers. Our top girl name Imogen, for instance, has never been on the U.S. Top 1000.
